Stainless Steel Round Manhole Cover Systems
Stainless steel round manhole cover; are corrosion-resistant access covers used to provide safe access in underground infrastructure systems, water tanks, and industrial tanks. Especially in municipal infrastructures, treatment plants, and food factories, it offers a much longer-lasting and more hygienic solution compared to galvanized or cast iron covers.
Why Stainless Steel Cover?
- ✔ High Corrosion Resistance: Provides superior protection against water, moisture, and chemicals, does not rust.
- ✔ Long Life: Does not corrode over time like cast iron covers, does not require painting or maintenance.
- ✔ Sealing: Prevents odor and liquid leakage thanks to its gasketed models.
- ✔ Aesthetic and Lightweight: Adapts to architectural projects with its modern appearance, easy to install.
Sectoral Usage Areas
Municipality and Infrastructure
Sewerage, rainwater drainage, and telecommunication access points.
Treatment and Water Tanks
Drinking water tanks, wastewater treatment plants, and seawater filtration systems.
Industrial Facilities
Food factories, pharmaceutical production facilities, and oil refineries drainage systems.
Technical Selection: AISI 304 or 316?
It is important to choose the right steel quality according to the environmental conditions of your project:
| Feature | AISI 304 Quality | AISI 316 Quality |
|---|---|---|
| Corrosion Resistance | Medium / Good | Very High |
| Salt Water / Acid | Low Resistance | Full Resistance |
| Usage Area | Indoor, clean water, light industry | Seaside, chemical, heavy industry |
Load Classes and Standards (EN 124)
Our products comply with international EN 124 and ISO 9001 standards. Correct cover selection according to traffic load:
- A15 Class: Light load for pedestrian and bicycle paths.
- B125 Class: Medium load for parking lots and sidewalks.
- C250 / D400 Class: Heavy vehicle traffic and industrial areas.
